Abstract: A navigational direction-indicating device includes a Global Positioning System (GPS), a display unit, an activation control unit, a navigation software for generating a direction guidance instruction according to positioning signals received by the GPS, and a plurality of light emitting elements arranged proximate to the display unit. After the navigation software generates the direction guidance instruction, the activation control unit generates activation signals according to the direction guidance instruction and corresponding to the light emitting elements, respectively, so as for a corresponding one of the light emitting elements to emit light, thereby allowing a user to receive the guidance instruction efficiently.
